Viewing Options

Tumble Center

These options rotate the camera about the viewpoint of the perspective camera or about any given world point.

View Center – To rotate the perspective camera about its viewpoint.

World Point – Causes the view to rotate around the point in world space specified by the World Point sliders (for example, 0, 0, 0).

Eye/View/Up

These sliders let you define a view by positioning the camera. The Eye position, View point position, and Up vector end point determine the view. The nine fields that define these positions contain decimal numbers. They represent, from left to right, the X, Y, and Z Coordinates for each of the three camera parameters. To see the camera as you modify it, use WindowDisplay > Toggles > Cameras .

NoteFor orthographic windows, two of the three Eye and View values must be the same, and two of the three Eye and Up values must be the same. If they are all different or all the same, the results are unpredictable. This is because viewing operations on orthographic windows are done on the window rather than the camera.

Zoom

The Zoom slider also takes a decimal number which defines the extent of the field of view of the camera. Values must be positive in the range of 0.2 to 179.

World Point

These sliders specify the position of the tumble center in world space.
